New Bulker-design approved
With an Approval in Principle (AIP), the American
classification society ABS has paved the regulatory
way for the market launch of a new bulker design.
The AIP was awarded to Deltamarin, Finnish subsidiary
of the Chinese Avic Group, and French tank manufacturer
GTT. The Newcastlemax bulk carrier with
dual-fuel engines should be able to comply with current
and future environmental regulations. The design
includes LNG membrane tanks from GTT integrated
at the rear. According to the partners, the tank
concept is designed to maximize the loading capacity,
whereby the additional tank has no influence on the
available cargo space or the dimensions of the ship’s
hull, »Such a design would allow owners and operators
to exploit the potential of LNG as marine fuel
without compromising cargo volume,« said Patrick
Janssens, ABS Vice President Global Gas Solutions.
HYBRID VESSELS
Wärtsilä and CSSC team up
Wärtsilä has signed a strategic development
agreement with Chinese state-owned shipbuilder
CSSC Huangpu Wenchong Shipbuilding Company.
The five year agreement is aimed at the joint development
of a hybrid powered dredger but could possibly
extend to other hybrid vessels as well. The purpose
of the agreement is to build a cooperation framework
and working mechanism for the research and
development of hybrid power systems. Wärtsilä will
support Huangpu Wenchong during the design and
construction phases with technology innovations,
system selection, performance calculations, and longterm
services. »Collaboration with industry partners
is at the very core of Wärtsilä’s Smart Marine approach
to raising efficiencies, and eliminating waste
throughout the shipping sector. This is one more example
of this philosophy, and we look forward to cooperating
with Huangpu Wenchong to create hybrid
powered vessels that will benefit the industry by lowering
costs, and benefit the planet by reducing greenhouse
gas emissions,« says Henrik Wilhelms, Director
Offshore and Special Vessels at Wärtsilä. »We are
very happy to be cooperating in this project with
Wärtsilä, a proven technology innovator and industry
leader in hybrid solutions for the marine industry,«
says Li Dong, Chief Engineer at CSSC Huangpu
Wenchong Shipbuilding Company. The initial work
will be based on a hopper dredger, a vessel that the
shipyard already builds. Evaluations will be carried
out to determine the most suitable hybrid solution for
that class of dredgers.
NEWBUILDINGS
Silverstream collaborates with SWS
Silverstream Technologies, an air lubrication
provider, has announced the
completion of three Joint Development
Projects with SWS (Shanghai Waigaoqiao
Ship Building) across two new energy
efficient vessels. The projects iclude
a 180,000 dwt dual fuel bulk carrier design
that has gained Agreement in Principle
from Lloyd’s Register, and a separate
300,000 dwt dual fuel VLCC design
that has achieved Agreement in Principle
(AIP) from both Lloyd’s Register and
ABS. The Joint Development Projects
will see Silverstream’s team of naval architects
and marine engineers support
the yard to integrate the system from the
very beginning of the design phase of the
new vessels. This reflects the growing demand
for the implementation of proven
clean technologies that drive operational
and environmental efficiencies on
newbuilds. By integrating clean technologies
at this early stage in a vessel’s lifecycle,
optimum efficiency gains can
be designed and priced into the overall
newbuild plan, lowering the barrier to
entry for the adoption of clean technology
even further.
