Tugs & Towing generally concentrates on European news but occasionally items of interest from further afield catch the eye, as with the delivery of a multifunctional vessel for the salvage division of the Peruvian Navy.

First sight of the vessel carrying the name BAP Moralesm gives the impression of a well-proportioned conventional small tug configuration, albeit with a higher freeboard aft perhaps than with usual tugs of similar size. A look at the capabilities squeezed into this 32m long vessel however indicate it is intended to complete a range of duties around the theme of towage, salvage and dive support.

It was designed in-house and built by the shipyard Servicios Industriales de la Marine S.A. (SIMA) and described as having ‘significant towing capabilities’, also with the ability to respond to maritime salvage incidents.

BAP Moralesm is 32m in length with a 12m beam and moulded depth of 4.5m on a finely-shaped double-chined hull. Tank capacities include 50,000 gallons of fuel and 17,000 gallons fresh water.

Propulsion is provided by a pair of Cummins QSK60 MCRS main engines each developing 2,200hp at 1,800rpm. Power is transmitted to ZF W11200 gearboxes each with 7.286:1 reduction, in turn connecting to 91.25” four-bladed Kaplan type propellers mounted on 8.5” diameter shafts. Performance figures are quoted as 52 tonnes bollard pull and a free running speed of 12 knots.

For what in other circumstances could be considered a moderately-sized shiphandling tug much equipment and capability has been shoehorned into the BAP Moralesm. A four-point anchoring arrangement is installed along with a launch and recovery system for deploying an open diving bell. Accommodation is provided for a crew of 20 along with additional space for up to 13 divers.

Servicios Industriales de la Marina S.A. (SIMA) is not a yard that appears regularly in this column so perhaps worth a closer look. SIMA dates back to 1845 and was established to satisfy the need to supply warships to the Peruvian government. Over the ensuing years, while the company has produced commercial vessels, naval vessels have dominated output of SIMA including in the 1980’s, a pair of Lupo class missile frigates for the Peruvian Navy.

The company has three yards at: Callao, Chimbote and Iquitos and as well as naval and commercial vessels lists metal working as one of its business lines with structures including steel bridges being part of its output. Ship repair including structural modifications such as vessel lengthening and widening is also on SIMA’s list of activities

Its tug building activity includes ASD models as well as the conventional drive example above and references include tugs up to 52 ton bollard pull for customers including Petrolera Transoceánica, Remolcadores Ultratug, Cosmos Agencia Maritima and TRAMARSA.
