Versatile workboat is a windfarm winner
Delta Marine’s vessel Whalsa Lass has demonstrated its versatility during recently completed works on the large windfarm off the coast of Grimsby UK for one of the ‘Big 6′ energy contractors.
The windfarm consists of 73 Vesta V112 3MW turbines located in water depths of some 15m and is now providing electricity sufficient to power up to 170,000 homes.
When the Shetland based operator chartered its Damen 2611 Multicat for a basic remit to serve as anchor handler for the cable laying vessel it had no idea what further scope of services the vessel would be called upon to perform.
The 26m Whalsa Lass features an 11.5m beam for great stability and a shallow 2.25m draft, advantageous for bringing cables to shore. Three Caterpillar C32 TTA main engines generate 1,902 bkW to provide a powerful 37 tonne bollard pull and a speed of 10 knots. A 100 tonne winch and twin Heila3 SL 230t/m knuckleboom cranes further add to a specification which informed client and operator alike that the vessel was capable of making a broader contribution to the project than was first envisioned.
