Renewable Energy Support Ltd (RES Ltd) takes delivery of 26m Typhoon Class Swath Crew Transfer Vessel – MCS Swath 1

The Ad Hoc Marine Designs Ltd. 26m Typhoon Class Swath ordered by Renewable Energy Support Ltd (RES Ltd) has been successfully delivered to operators Maritime Craft Services (Clyde) Ltd (MCS) after completing final sea trials in July in Taiwan.

 

 

 

 

 

 

The design, by Ad Hoc Marine Designs, of the 26m CTV Swath is an all-aluminium light weight robust & durable construction to BV class and MCA regulations and is based upon the experience of previously proven swath hull designs. It is uniquely designed to satisfy both slow speed and loitering operations at the turbine as well as high speed. This unique hull form satisfies these two competing requirements that resulted in an advanced Swath hull form with 20% increase in displacement, 50% reduced coupling and 20% increased damping without sacrificing resistance. It has been tailored for the demands of the Windfarm market. Designed to run in Hs = 2.0m at service speeds of 25 knots without any speed restrictions or uncomfortable motions that is associated with conventional vessels.

 

 

 

 

 

 

 

The operational role is enhanced by a powerful Island Engineering Motion control system that reduces seasickness, fatigue and vessel downtime to a minimum annually. It also features an advanced heave dampening mode that significantly reduces heave when at idle or stationery at the tower. Driven by two Man D2862 LE 466 diesel engines rated at 1029 kW IMO Tier 2, EPA Tier 3 compliant with a simple lift out from engine room via a hatch on the main deck. Each engine drives a Centa carbon fibre shaft to minimise weight coupled to a heavy duty Hundested CPP propeller.

On the first rough sea trial the vessel performed beyond expectations, which prompted Dirk Kuyt of MCS to state:

“During sea trials with the MCS SWATH 1, in Beaufort 4-5 from Southerly direction, off Suao Port, Taiwan I became aware what a 100% SWATH is all about. With wave height of 1,5 – 2 m,  there was no motion or acceleration at all and when at full speed putting the rudder hard over no heeling occurred. Truly amazing! Maximum speed in front of everything 27′ and average of 25′/hr. All main machinery are just below main deck for easy maintenance and in my opinion this is the best SWATH CTV in Europe or best CTV in Europe full stop.”

A build and final sea trial video of the 26m Swath CTV MCS Swath 1 taken during the tail end of Typhoon Nepartak on July 12th 2016 is shown here:
