Tug masters experience the effects of a tug's stability every day when manoeuvring their vessel, either free sailing or when assisting ships. During tug operations, a number of forces and combinations are working on a tug – such as towline, hydrodynamic, steering and propulsion forces – often at or near their maximum with respect to the tug's stability. It is, therefore, not just desirable but necessary for tug masters to have at least a basic idea of the elements of stability. They need to know where the limits are, and what the consequences could be, if the tug or tug handling practices don't conform to the rules of stability – not only in normal circumstances but also when extreme conditions, such as dense fog and storms, occur. The consequences can be very dramatic. Numerous harbour tugs have capsized, often with tragic consequences. In the tug capsizes known to have occurred between 2010 and 2015, more than 45 people have drowned. This educational guide to stability specifically for tugs aims to provide this important information to tug masters. It is written in a manner readily understood by all tug masters, regardless of their education, formal qualifications, nationality or operational backgrounds. The text is accompanied by numerous illustrations and photographs. In writing this handbook, the authors master mariner and pilot Captain Henk Hensen and naval architect Dr. Markus van der Laan have focussed on the practical aspects of stability, tug design and equipment and also on the consequences of unsafe procedures. Their emphasis is on harbour tugs, although several of the topics covered apply equally to seagoing tugs." The authors have produced an original and valuable training guide which will increase the knowledge of tug stability within the industry, and so enhance the safety of tugs, tug crew and the ships they support. It is hoped that this increased knowledge will indeed enhance safety and help to protect the marine environment." Ashok Mahapatra Director, IMO Maritime Safety Division. "This tug stability book will greatly contribute towards safer towage operations by enhancing the working knowledge of tug masters. It is an important publication for all tug masters and towage managers, no matter what facet of the towage industry they are engaged in." Arie Nygh ITA Patron; Managing Director, SeaWays Consultants.\r\n

Damen delivers its first hybrid tug boat to the Royal Netherlands Navy on februari 20, 2016.\r\n
The first of a series of three ASD TUGs 2810 Hybrid was navigated into the Den Helder harbour by the Royal Netherlands Navy (RNLN) on Saturday, February 20th. This hybrid tug that bears the name NOORDZEE is almost 29 meters long and is the first standard hybrid tug supplied by Damen that the RNLN will employ.\r\n
The contract for the three ASD tugs emphasises the good cooperative partnership that exists between Damen and the RNLN, as well as their shared vision. Both parties believe in a durable future and have chosen a sustainable option with the ASD TUG 2810 Hybrid.\r\n
At this time, the RNLN has four conventional tugs in Den Helder at its disposal. However, these older vessels do not have sufficient power to tug new ships such as the HNLMS Karel Doorman, HNLMS Rotterdam and the HNLMS Johan de Witt. Furthermore, the old vessels still make use of normal propellers with rudders with a restricted manoeuvrability and no longer fit the vision of sustainability that the RNLN has for the future.\r\n
The state-of-the-art ASD TUG 2810 Hybrid is one of Damen's standard tugs and, with its hybrid propulsion system, is powerful and durable. The vessel is provided with two rudder propeller units for optimum manoeuvrability and is able to sail on full electric power by means of a set of batteries and also diesel-electric on the generator set. When full pull is required, both main diesel engines are used, giving a maximum bollard pull of 60 tonnes, ensuring that all heavy duty tug jobs can be realised.\r\n
The RNLN was explicitly looking for a standard tug which was very environmentally friendly, as well as being powerful enough to realise heavy operations. The Navy contracted Damen for the project due to the fact that hybrids and sustainability are standard design concepts for Damen. In total, the RNLN, in cooperation with the Swedish Navy, has ordered five vessels, including the hybrid tugs. The two additional Swedish tugs are also of a standard design, but designed for operations in icy waters.\r\n
The NOORDZEE was sailed by the RNLN from Damen Shipyards Galati in Romania to the port of Den Helder. The two other ships, the WADDENZEE and the ZUIDERZEE will be delivered in mid-March and mid-June. Damen is proud to have the opportunity to cooperate with the RNLN, in a partnership which emphasises the vision of sustainability and the diversity of both parties.
It is reported that the 2008 built Damen ASD2810 sisters SL Cayman (Imo 9516284) (ex. Smit Cayman - 2015) and the SL Montserrat (Imo 9516272) (ex. Smit Montserrat - 2015) has been sold to Masco JSC on the first day of February 2016 and renamed respectively Helius and Grumant. Both tugs are built by the Damen Song Cam Shipyard – Vietnam under yard numbers Smit Cayman 511551 and Smit Montserrat 511550. They have a length o.a of 28.67 mtrs a beam of 10.43 mtrs and a draft at sides 4.60 mtrs. The two Caterpillar 3516B TA HD/C diesel engines develops a total output of 3,678 kW (4,930 bhp) which results in a free sailing speed of 13.5 knots and a bollard pull ahead of 60 tons.\r\n

It is reported that Boskalis Offshore purchase the two DPII Anchor Handling Tug Supply vessels Sea Bear (Imo 9185932) and Sea Lynx (Imo 9178410) from Deep Sea Supply. The two vessels will be renamed Union Bear and Union Lynx. The AHTS, type KMAR404, will be drydocked this weekend at the Damen Shipyard - Schiedam; Netherlands. The 1999 built sister vessels have a length o.a. of 73.50 mtrs a beam opf 16.40 mtrs and a draught of 6.90 mtrs. The Bear is built by Kværner Kleven Leirvik under number 271 and the Lynx by Kværner Leirvik under number 281. The two ainengine develops a total output of 11.240 kW (15.000 bhp) (Photo: D. Thompson)
Alongside each other for one last time! Tuesday morning Ron Damman received a call from an employee of the harbor office: 'Are you busy?' 'Yes I'm quite busy, why?'. They told me they wanted a picture of all the tugboats alongside each other for one last time while it still could. Of course this was something I really wanted to do, so I went there just after noon. The first new tugboat, NOORDZEE, was on its way to Den Helder and the two oldest tugboats, LINGE and REGGE, are about to leave the Port of Den Helder.
Above at the photo you see, from left to right, de REGGE, ROTTE, HUNZE, LINGE en GOUWE (the 'A' boats) next to those you can see the BREEZAND and the MALZWIN. The BALGZAND is still at the naval shipyard for maintenance. After some 'research' Ron can tell you that the four 'A' boats will leave for England via Damen Trading. The LINGE, REGGE, ROTTE and the HUNZE are sold to MTS Towage in Brixham and Falmouth. The only "old" tug that will stay in service off the Royal Dutch Navy in the Port of Den Helder is the tug GOUWE.

On Tuesday 9th February we received the message that Mr. R.W. (Rom) Scheffer passed away at the age of 85 years. During the sixties, seventies and eighties of last century Mr. Scheffer was a remarkable personality in the world of shipping. After his training to become an officer on board of ships, he sailed for some two years on freighters and passenger ships, i.e. for Van Nievelt Goudriaan and for KJCPL on Tjisadane.
Soon, it struck his masters that Rom Scheffer had quite some commercial qualities. At the age of 22 Mr. Scheffer decided to work ashore. He accepted jobs for foreign companies in South-Korea, the U.S., Hong Kong, Kuala Lumpur and Singapore. A.o. he chartered ships for a mining company that exported ore from Malaysia to Japan. When the mines were more or less exhausted and mergers took place, he was looking for a new challenge.
His reputation was already well-known and he was recommended to Mr. A. Lels, the man who, at that time one of the directors of L. Smit & Co, laid a plan on the table to establish a shipping company for supplying drilling platforms in the North Sea. In 1964 at the age of 33 Mr. Scheffer became the first employee and the first director of Smit-Lloyd, the company that Mr. Lels had in mind.
Thanks to the energetic approach of Rom Scheffer the company became a renowned firm in the offshore world and oil-industry. Oil-production at sea was still in its infancy and Mr. Scheffer was a pioneer as far as supplying drilling platforms were concerned. The original plan was to have seven suppliers built, however for each ship there was already a contract concluded before even being commissioned. After only some years dozens of Smit-Lloyd suppliers were sailing the oceans. Subsidiaries were established in a.o. Australia, Greece and the U.S.
In 1976 some of the subsidiaries of L. Smit & Co's Internationale Sleepdienst, among which Smit-Lloyd merged. Still the Smit-Lloyd vessels kept on sailing under their own wellknown colours for quite some time. One year after the merge Rom Scheffer was asked to accept the job of CEO of Smit International as a whole. Although his heart was still with Smit-Lloyd he accepted this difficult task. For ten years he was the leading personality of this world wide well-known towage and offshore company. During that period of time he encountered many problems. Both the markets for towage as well as offshore activities decreased. Yet, thanks to his inventive, however difficult decisions Smit International survived.
By 1987 Mr. Scheffer had to decide to step down. His health caused him too much troubles and he was right when he stated: You can't do this job in a more quiet atmosphere. Still after 1987 the maritime markets were facing difficult times. As a consequence in 1996 Smit-Lloyd was sold to the American Seacor company. That's certainly a fact that hurted Mr. Rom Scheffer. Although retired Mr. Scheffer kept on following the weal and woe of Smit International, the towage market as well as the situation in the offshore industry.
In 2006 he persuaded me to write the history of 'his' company, viz. the book "The Smit-Lloyd Story". An outstanding man in the maritime world passed away. He leaves his marks in the offshore history.
