Special tools and spare shackles
including the main electrical switchboards, the control and service cabinets and additional fuel and lube oil tanks. On looking at the electrical installation, designed and fitted by Marine and Industrial Electrics Ltd, once again the big ship look is present, along with functionality and robust service capability. Moving aft through another watertight door, we end up in the lazarette, where we find the steering gear heads and extra hydraulics and pumps to the tow wire control pins and lug. As we moved around and looked at the aesthetics outside and throughout the heart of this little ship, she is clearly a solidly built steel vessel designed to take the knocks and rigours of years of hard work in what is a very tough industry on small tugs. To protect the steel she has been coated throughout, topsides and underwater, using Altex Coatings' proven paint systems for workboats.
The brief for Altex Coatings was, as is always the case with ShipCo, a good, reliable system that will stand up to the harsh environment she will be working in for long periods. Utilising Carboline's time-proven products, the PT May has a superior coating system to last her for many years. Carboline Carbomastic 615 was chosen as the epoxy high-build, as this coating exhibits outstanding moisture and surface tolerance during application, low temperature cure capability and very fast cure response for quick return to service as required to meet the building time schedule.
Her underwater surfaces carry a coat of semi-hard Altex Sea Barrier 4000 as a first coat, along with two coats of the ablative Altex Sea Barrier 3000. Both products have IMO approval over the Carbomastic 615 high-build system.
Main machinery space To say we were impressed with the PT May would be an
under-statement, as this tug will have to be the leader for many more years to come. She is well built, is actually good-looking and punches well above her weight. She has demonstrated excellent sea-keeping ability with no bad habits. One has to agree that for $3.2 million she is a lot of boat for a small working tug. She has been built with the no-nonsense, brutally tough, functional attitude to construction that ShipCo has become recognised for.
