Hatch covers and bearing pads
for China Shipping’s new containership fleet
renewal programme
Both vessels spearhead the
major eight-ship,
70,000dwt fleet renewal
programme currently
underway by China
Shipping and feature hatch
covers designed and
supplied by TTS Ships Equipment’s Bremen,
Germany and Shanghai, China companies,
TTS Ships Equipment GmbH and TTS Hua
Hai Ships Equipment Co Ltd.
New Pudong was built by China’s
Hudong-Zhonghua Shipbuilding (Yard No.
H1263A), while New Dalian was built by
Dalian New Shipbuilding Heavy Industries
Co Ltd (Yard No. C5600-1). Both vessels,
the largest of their type yet built by the
respective shipyards, feature TTS designed
lift-on/lift-off pontoon hatch covers designed
for non-sequential opening/closing.The
hatch cover panels are designed for lifting by
shore-side cranes and can be stacked either
on adjacent covers or ashore.The hatch
covers are so arranged that longitudinal joints
between the panels align with spaces between
the containers on deck and in the holds.
A total of 44 hatch cover panels have been
supplied to each China Shipping
newbuilding, covering a total day-opening
area of 6,364m2 .Hatch No.1 is fitted with
two panels (12.6m x 15.74m), hatch No.2
with three panels (12.6m x 25.89m), hatch
No.3 with three panels (12.6m x 30.96m),
while hatch No. 4-15 have three panels
(12.6m x 36.04m).
The hatch covers are designed for a
uniformly distributed load of 1.3 ton/m2 B
for
hatch covers of Hold No. 1-4, and
1.05 ton/m 2 for the covers of Hold
No. 5-15. Each hatch cover is sufficiently
strengthened for a container stack load
of 90 tonnes for a maximum of six tiers
of 20ft containers per stack, or 120 tonnes
per six tires of 40ft container per stack.
45ft containers can be loaded from the
third top tier of 40ft containers on
Hatch No. 3,5,9,12 and 15, while 45ft
containers can also be loaded from the first
tier on the hatch covers for Hatch No.1,7
and 11.
Both China Shipping vessels also feature
TTS Ships Equipment’s unique, patented,
OptiPad hatch cover bearing pad design,
part of the company’s EverEst range of
new generation hatch cover bearing pads
incorporating advanced technology
materials.The OptiPad design is made of
PTFE in the form of a ‘weave’ fabric, which
results in a highly effective bearing pad able
to absorb very high loadings while
accommodating considerable movement of
the hatch cover/coaming interface.
The start of 2003 has been a busy one for
TTS Ships Equipment GmbH in Bremen and
TTS Hua Hai Ships Equipment Co Ltd in
Shanghai with ship deliveries.
Besides the two large containerships for
China Shipping, a further six TTS hatch
cover-equipped vessels have been delivered
by Chinese shipyards:
• BBC Europe, 7,000dwt multipurpose
cargoship from Xingang Shipyard (Hull
No. SB325) for Germany’s Brise
Schiffahrts – TTS hydraulic, multi-folding,
pontoon hatch covers
Two of the largest
containerships yet built in
China have recently been
handed over to China
Shipping, the 5668 TEU pair
New Pudong and New Dalian.

containership from Jiangdong Shipyard

China has become an important country
for TTS Ships Equipment and the scope
of supply of hatch covers outlined above
highlights this.With its own dedicated
operation in China,TTS Hua Hai Ships
Equipment Co Ltd, in Shanghai (a 50:50
joint venture between China State
Shipbuilding Corp and TTS Ships Equipment
AB),TTS is able to meet the needs for all
dry cargo handling systems requirements for
newbuilding under construction at Chinese
shipyards locally, backed-up by the hatch
cover ‘Centre of Excellence’ of the group in
Bremen, Germany and the ro-ro ‘Centre of
Excellence’ in Gothenburg, Sweden.
