HELSINKI: Wärtsilä has developed propulsion systems that are capable of operating with Environmentally Acceptable Lubricants (EALs) and comply with the US Vessel General Permit 2013 (VGP-2013). Wärtsilä is among the first marine propulsion solutions suppliers to achieve this compliance for complete propulsion packages, the company said in its press release.
For vessels operating in US waters, VGP-2013 mandates the use of EALs in all oil-to-sea interfaces unless technically unfeasible. VGP-2013 was issued by the US Environmental Protection Agency (EPA) and is applicable to all vessels sailing in US coastal waters.
Wärtsilä began work on developing an effective solution in 2013, working together with numerous EAL suppliers. EALs have since been extensively tested with Wärtsilä steerable thrusters at the Wärtsilä Propulsion Test Centre in Tuusula, Finland. This testing has provided Wärtsilä with a deep technical understanding of the EAL impact on marine propulsion systems.
The first vessels to be fitted with Wärtsilä’s VGP-2013 compliant propulsion package are four BigRoll MC Class module carriers currently under construction at the COSCO shipyard in Dalian, China. The four state of the art MC class vessels (DP2 prepared, flush deck, 1A ice class and high service speed) will be operated by BigRoll Shipping for large module transportation services for offshore and onshore projects. The propulsion equipment will include Wärtsilä main engines, Wärtsilä tunnel thrusters (WTT) and Wärtsilä controllable pitch propeller systems (WCPs).
