The delivery of the last of a series of six geared handysize carriers from Yangzijiang Shipbuilding for Bulgaria-based ship operator Navibulgar is scheduled for August.

The shipowner ordered 4+2 45,000dwt Handysize bulk carriers in 2017. The design for the series was developed and designed by ship designers Bluetech of Finland, and represents an evolution of the Bluetech 42 design.

MAN ES two-stroke propulsion machinery has been specified for the BT45, in the shape of a five-cylinder model of the G50ME-C design. The contracted maximum continuous output of 6,800kW at 96.6rpm denotes the specification of the engine in its R4 rating, leading to an economical continuous service rating of 5,100kW at 87.8rpm.

The vessel is understood to have outperformed specified fuel efficiencies during sea trials by up to 4%. The design incorporates BlueFin technology, which contributes to its high propulsion efficiency.

Navibulgar Executive Director Aleksandar Kalchev commented. “Both series have met our initial expectations and today we are so happy to own and run such a fleet. The design/ships are so flexible and easy to be operated. We have been impressed by their ability to keep good performance in rough seas, but the real advantage comes when they are slow steaming in normal weather conditions.”

The 1C ice class vessels offer operational flexibility for Bulgaria-based ship owner Navibulgar, which is among the largest operators of handysize shipping in Europe. Access to ports in Black Sea and Sea of Azov is restricted during the ice season, along with parts of the Baltic Sea.

Total underdeck cargo capacity is some 59,800m3 on a grain-equivalent basis, which the designer Bluetech claims is the largest among ships of that design. The underdeck spaces are designed to accommodate the main bulk commodities, including ore, grain, coal, fertilisers and timber products.

The BT45 is laid out with five holds accessed through wide hatchways served by folding covers and plumbed by four 30 tonne electro hydraulic deck cranes. The hatches to Nos 2,3, 4 and 5 holds span 21m of the vessel’s 32m breadth.
