This featured vessel is  ‘ORCA III' our GRP Wildcat 53 / 16m catamaran's. She has been built for Angus Campbell, based on the Isles of Harris in the Outer Hebrides, Scotland. This is the third vessel Angus has commissioned from Safehaven Marine, the first being an Interceptor 42 in 2004, in 2007 he commissioned an Interceptor 55 which he has operated as a passenger vessel on the St Kilda run, a 100nm voyage from The Isles of Harris out into the North Atlantic, and must surly represent the most challenging of operational roles a commercial vessel must endure, often facing 6m seas on the voyage and regularly caught in heavy weather on the return trip, the Interceptor 55 proved a safe, seaworthy vessel. Angus will use ORCA III on this run, but will also use her for a multitude of other operational roles, these being windfarm support, hydrograpic survey and long range passenger and dive support, and for each role she has been specifically adapted. For windfarm support she features a heavily reinforced and fendered bow allowing crew transfers to windfarm structures and incorporates 12 reclining 'air craft' style passenger seats, each with a table in front providing a comfortable environment for passengers.

For hydrographic survey work she is equipped with a moon pool and multi-beam sonar head deployment frame which can be removed when not required, this has been developed and refined by Safehaven over several previous survey vessels they have built. She features a dedicated survey bench for hydrographic equipment. For her St Kilda run, and for the long-range offshore work she will do the vessel has been built to comply with MCA Catagory 0, un-restricted service range, incorporating 5,000 litre fuel capacity, high survivability with 8 watertight compartments and complying with Cat 0 damaged stability requirements. Her hulls scantlings have been designed for Lloyds SSC area G1 and are 'substantial' with transverse framing at 500mm centres providing her with the strength needed working this far offshore. She is equipped with an Icom M800 SSB radio and live aboard facility with 8 bunk berths, full galley with a 240v cooker & hob as well as a large freezer, all powered by a 12kw generator providing onboard AC power. The vessel features a hydraulic power supply powering twin 95kgf bow thrusters, and a HIAB  crane mounted on the aft deck. She is fitted with her own 5m RIB carried on her spacious (28m2) aft deck on a cradle, and is launched by crane, allowing passenger transfers ashore from remote destinations. In addition she has a dive platform and divers ladder on the transom, and to assist dive operations she is fitted with twin bow capstains / windlasses and an aft capstain on her transom.

Safehaven's Wildcat 53 is a high buoyancy bow, twin chine symmetrical hull catamaran form, that has proved very successful in Safenaven's 'Wildcats',  providing exceptional levels of sea keeping and performance. The design is 16m  moulded (17m LOA) with a 6.1m / 20ft  beam and differs from the last two Wildcat 53 windfarm support vessels, supplied by Safehaven to Island Shipping in 2010 and 2011, both of which have been working successfully on UK windfarms for the past 18 mths, in having a single level superstructure design, as opposed to a raised bridge deck design, this gives the advantage of allowing f/wd visibility for all passengers which Angus felt was important for passengers on the long transit durations his passengers undertake in Cat 0 service.

Angus chose GRP again as he knew that Safehaven were no stranger to building exceptionally strong GRP hulls, the Wildcat 53 has the same heavy duty scantlings as their renowned pilot boats which are often subject to severe impacts in rough weather, this produces a vessel that can withstand tough use in harsh weather far offshore. GRP provides many benefits, being a homogeneous structure it is very strong, it gives a high standard of external finish with the advantage of zero maintenance and perfectly compliments Safehaven’s graceful designs, resulting in a very striking looking vessel.

Below, for hydrographic work she is fitted with a moon pool and multi-beam sonar head deployment frame.


‘Orca III is powered by twin Scania D16 700hp engines and Twin Disc MG 5135 quick shift gearboxes driving conventional sterngear:  762mm" props on 90mm shaft  and large balanced stainless steel rudders. Angus required her to be able to run at 18-20kts on her 200n/m round trip to St Kilda in the heavy weather he experiences and she easily surpasses this, with a 24kts maximum speed and 22kts operational speed on her 30,000kg displacement
