10 Important Things Deck Officers Must Check During Cargo Watch
- Plan and Monitor Loading and Discharging of Cargo.
- Have Knowledge of IMDG Containers Loaded Onboard.
- Handle Reefer Containers With Care.
- Check Lashings Of Out of Gauge Cargo (OOG)
- Have Proper Visual Inspection of Ship’s Draught.
- Check Ship’s Ballast and List.
How important is securing any cargoes on deck?
The proper stowage and securing of cargoes is of the utmost importance for the safety of life at sea. Improper stowage and securing of cargoes has resulted in numerous serious ship casualties and caused injury and loss of life, not only at sea but also during loading and discharge.
What are the 5 different ways of securing cargoes?
Examples of blocking: front wall, wedges, dunnage bags, chocks and beams. Examples of lashings are web lashings, loadbinders with chain and fixed winches. The equipment can be used in different applications e.g. top-over lashings (friction lashing), direct lashings and loop lashings.
What is the purpose of SWL for securing cargo?
“Maximum securing load (MSL) is a term used to define the allowable load capacity for a device used to secure cargo to a ship. Safe working load (SWL) may be substituted for MSL for securing purposes, provided this is equal to or exceeds the strength defined by MSL.”
How should you perform watchkeeping in port?
Principle of watchkeeping in Port
- Maintain and ensure that safe working practices are followed in cargo and other operations,
- Ensure that the cargo stowage is as per plan,
- Inspect the condition of the cargo,
- Check sounding and control ballast operations,
What is deck Watchkeeping?
Watchkeeping or watchstanding is the assignment of sailors to specific roles on a ship to operate it continuously. On a typical seafaring vessel, be it naval or merchant, personnel “keep watch” in various locations and duties across the ship, such as the bridge and engine room.
What are the three types of ship stability?
There are three types of equilibrium conditions that can occur, for a floating ship, depending on the relation between the positions of centre of gravity and centre of buoyancy….Intact Stability of Surface Ships:
- Stable Equilibrium: Study the figure below.
- Neutral Equilibrium:
- Unstable Equilibrium:
Why does a deck cargo be so distributed and stowed?
Deck cargo shall be so distributed and stowed 2) as to ensure that the ship will retain adequate stability at all stages of the voyage having regard in particular to: losses of weight in the ship, including in particular those due to the consumption of fuel and stores; and.
What is broken stowage?
Broken Stowage: Space lost between boxes, between vehicles, around obstructions and over (above) cargo/vehicles due to irregular shapes/configuration, separation requirements and fire lanes.
What manual is that where you can find How do you secure the cargo to be loaded?
Cargo Securing Manual specifies arrangements and cargo securing devices provided on board the ship for the correct application to and the securing of cargo units, containers, vehicles and other entities, based on transverse, longitudinal and vertical forces which may arise during adverse weather and sea conditions.
How do you calculate lashing capacity?
LC = Lashing capacity (permissible pulling force in daN) (1kg ≈ 1 daN) STF = Standard tension force Normally remaining tensio- ning force in daN of a ten- sioning element, with a manual pulling force (SHF) of 500 N. Equals the pre- tension force required for the calculation of a tie- down lashing.
What do you need to know about the timber deck code?
The Code provides: .1 practices for safe transportation; .2 methodologies for safe stowage and securing; .3 design principles for securing systems; .4 procedures and instructions to be included in ships’ cargo securing manuals on safe stowage and securing; and .5 sample checklists for safe stowage and securing.
What are the requirements for building a deck?
And so the following topics, covenants, easements, setback and variances are ancillary issues that over arch the general regulation of construction. For these, you must drop in to your local city building department and chat with the officials about any covenants that may specify size, style, and location or material restrictions for you deck.
How big should the supports be when stacking decking?
When stacking decking bundles, supports (dunnage) should start approximately 8-in (203 mm) from each end and be spaced approximately 2-ft (0.61m) on center. In addition, supports (dunnage) should line up vertically/perpendicular to the decking product. Adjust support blocks (dunnage) accordingly if bundles are loose.
Is there limit to how close a deck can be to another building?
There are usually limits to how close your deck can be to another building. Be sure to find out – You don’t want any surprises after its built. A variance is a rarity. Basically any regulation can be challenged and depending on your circumstances, may be set aside or “varied”.
What’s the maximum width for a 2×10 deck?
The rule of thumb says that 15 feet is your maximum allowable span for a generic 2×10 deck joist. In my experience this rule of thumb always comes in shorter than the building codes allow—which is a good thing! This rule also assumes you are spacing your joists 16 inches on center.
Like a house, or any other building, a deck must be designed to support the weight of people and objects placed on them, as well as lateral and uplift loads that can act on the deck as a result of wind or seismic activity. The 2006 versions of both the IBC and IRC contain language outlining the general design requirements of structures.
How many decks in the US are code compliant?
There are approximately 40 million decks in the United States, and only half of those are code-compliant. Deck safety is a real problem. Every year we hear about decks that collapse under the weight of people or snow load.
Is it dangerous to build a deck without a code?
Deck safety is a real problem. Every year we hear about decks that collapse under the weight of people or snow load. Improperly built decks can be dangerous. Local codes were created to keep us safe, and many existing decks do not meet current safety codes.
