OCEAN TRANSPORTATION – CHEVRON

Additional Chevron requirements (outside

and above contractual agreements with

Idesa).

Main topics

• Vessel and office audit

• Inmarsat tracking 24/7

• Limited acceleration forces

• 25% contingency added to theoretical

weight of cargo (crane capacity and

deck stress)

• Marine Warranty Surveyor Idesa

• Marine Warranty Surveyor Chevron

OCEAN TRANSPORTATION – LIFTING

Original rigging position Adjusted rigging position

Due to an incorrect Centre of Gravity the location of rigging had to be adjusted

OCEAN TRANSPORTATION – STOWAGE

Hold:

1 coke drum and transit cargo

Deck:

5 coke drums

OCEAN TRANSPORTATION – SEA FASTENING

Longitudinal / Vertical sea fastening by

certified BigLift wire system

Transverse sea fastening by shear plates

(T-stopper)

OCEAN TRANSPORTATION – SHIP MOTIONS

Happy Dynamic is equipped with Octopus system

• Measuring actual acceleration values

• Predicting future acceleration values

• Captain decision support system

OCEAN TRANSPORTATION – SHIP MOTIONS

Z-accelerations:

Combination of heave and

vertical component of the pitch

acceleration.

Results in vertical forces

(uplift/downforce) between

ship and cargo.

X-accelerations:

Mainly due to surge motions

of the vessel.

Y-accelerations:

Combinations of the sway and

the horizontal component of

the roll-acceleration.

Results in longitudinal and

transversal force interaction

between ship and cargo.

OCEAN TRANSPORTATION – SHIP MOTIONS

Departure Aviles delayed due to

- Weather forecast

- Spanish custom offices closed around X-mas

- Confusion on instructions/advise from MWS

DNV

(BigLift)

X 0,35 0,3 0,24

Y 0,65 0,5 0,32

Z 0,5 1,0 0,29

Maximum allowable accelerations (m/sec2)

OCEAN TRANSPORTATION – X-ACCELERATIONS

X-Accelerations on cargo due to

surge motions of the vessel.

X-accelerations for both cargo items nearly

equal. (mainly linear

surge motion)

OCEAN TRANSPORTATION – Y-ACCELERATIONS

Y-Accelerations on cargo due to sway

and rolling motions of the vessel.

Values according to DNV calculations.

Peak in y-accelerations due to heavy rolling

motions near Panama.

OCEAN TRANSPORTATION – Z-ACCELERATIONS

Z-Accelerations on cargo due to heave

and pitch motions of the vessel.

Values according to DNV calculations.

Peak in Z-accelerations just after departure in Aviles.
