According to Germanischer Lloyd (GL),
the classification society has been
authorised by the Panama Maritime
Authority to offer its extended dry
docking (EDD) programme for vessels
flying the Panama flag.
GL says that the Panama flag
state acknowledges the technological
advancements which have enabled
environmentally safe in-water inspections
and maintenance, and the improvements
in corrosion resistant materials, including
the endurance and effectiveness of
The EDD scheme offers ship owners
and operators, who implement the
current technological options, the option
to extend normal dry docking intervals by
two and a half years. It concentrates on
newbuildings and young container
vessels, general cargo and multipurpose
vessels. The first five-year class renewal
dry docking is replaced with in-water
surveys at 2.5 years and five years, with
the first dry docking taking place at 7.5
years. The sequence continues until a
second dry docking at 15 years, after
which the docking schedule reverts to the
The scheme offers savings in docking
costs, plus reduced off-hire and more
flexible options for arranging inspections
and meeting charter party requirements.
Entry requirements include flag state
programme approval and class notation IW
(in-water). All ships participating in the
EDD programme must have a GL-approved
comprehensive planned maintenance
system for the hull as well as for machinery.
In addition, the ship must be fitted with a
shaft bearing and sealing system of
approved design with implementation of
regular monitoring procedures.
GL’s EDD programme participants are
said to benefit from detailed knowledge
of where and when inspections and
repairs must be performed, early
warning of degraded hull condition that
helps to avoid costly surprises in
dry-dock, and an overview of fleet
status that allows avoidance of similar
problems with sister vessels.
With this authorization, Panama,
which oversees the largest shipping
register, now joins other maritime
administrations like Greece, Antigua &
Barbuda, Jamaica, and Germany who have
agreed to the GL’s EDD procedure.

April 2011 SHIPS AND SHIPPING
The innovative Hull Surface Treatment
(HST) technology has again proved to
be deadly efficient in killing and
removing hull fouling.
The treatment was carried out on two
fifteen-metre strips on the port side of the
Teekay Corporation’s ‘Iron Monarch’,
allowing for comparison between the
treated and untreated sections. HST was
applied on the December 15, 2010 and
photos were taken on January 25, 2011.
The ship had steamed for a total of 24
days in that period.
The photos leave no doubt that this
technology is a highly effective solution for
hull fouling in 2011. The fuel saved by a
vessel if its hull were kept in the condition
shown by the photos of the treated
sections of this hull as compared to the
untreated sections would far out-weigh the
cost of applying HST regularly.
Hull Surface Treatment (HST)
technology is a new environmentally
friendly treatment. T&C Marine is the
international licensee for the technology
that eliminates the growth on the laminar
flow sides of a ship using no chemicals,
detergents or substances which are foreign
or harmful to the marine environment.
The HST system utilises thermal shock to
instantly kill the growth and its spores.
According to T&C Marine, the system
is completely safe, and unlike most
traditional hull cleaning methods such
as hull scrubbing, it has no negative
impact on anti-foul coatings or the
HST is thus highly cost effective,
assisting ships to reduce their fuel
consumption, conserve energy and emit
lower greenhouse gases by ensuring that
their hulls are clean and smooth – free from
bio-fouling organisms such as slime, algae,
weed and/or molluscs. HST also ensures
that the hull fouling on commercial and
military shipping is reduced and/or
eliminated as a vector for the introduction
of imported marine pests (IMPs).
HST has won numerous national
and international awards and was
recently selected by the Royal Australian
Navy as its preferred underwater hull
An Australian innovation, HST has
global potential and, according to T&C
Marine, could save up to 40 million
tonnes of fuel oil consumption, reducing
greenhouse gases by up to 120 million
tonnes per annum.
