Vessel and barge track and monitoring

1. Coal Barge Schedule Optimization
Feb. 2020

2. Executive Summary
» In an attempt to reduce or eliminate these delays, Sinarmas Mining and Smartfren conducting assesment to develop a
modeling framework and decision support system to facilitate the planning and management of BC’s transshipment
operations.
» The system utilizes fast search algorithms that deliver efficient schedules, minimizing the cost of delays and additional
resources required.
Scientific
Approach
» Digitalization of transhipment process utilizing AIS as location sensors
» Involving of coal-barges/tug boats, Floating Cranes and Coal Mother Vessels
Scope
» Feasibility on vessel where about for safety and security
» More effective and efficient operation
Business
Impact
Backgrou
nd
» This focuses on BC’s maritime operations in Indonesia, where coal is transported from mines to ocean-bound vessels
via roads, rivers and off-shore. Currently, transportation delays are causing BC to lose tens of millions of dollars per
year in demurrage and detention penalties.
» Additional resources such as barges and floating cranes can be hired in advance to minimize the impact of delays, but
their economic benefit is often unclear.

3. » Barges rotate from BC’s hub to a supplier jetty, where they are loaded, to the port,
where they are discharged onto a client vessel, and back to the hub.
» Waiting for available loading and discharging resources can happen at every stage.
Barges logistic process

4. » Overall, a voyage (from hub to hub) can require anywhere between 3 and 10 days, and therefore a barge voyage
needs to start well in advance of the anticipated arrival of the customer vessel in order to be able to start
discharging on time.
» Each vessel has an estimated time of arrival (ETA, see Figure ), mutually agreed upon by Noble and the customer
at least two weeks in advance.
» Also mutually agreed upon is the laytime, a time window that starts with the vessel’s arrival, after which the vessel
has to be fully loaded
» On rare occasions, loading finishes before the end of the laytime, resulting in despatch, a bonus for BC, typically at
half the rate of demurrage.
» The estimated time of arrival (ETA) of a vessel denotes the start of the lay time, i.e., the maximum time window in
which the vessel has to be loaded. Overruns result in demurrage penalties (left), and early completion in despatch
bonuses (right).

» Continuously track vessel activity being
conducted across upstream and
downstream operations
» Gain a competitive advantage in terms
of understanding upstream trends to
better assess the next work site
» Monitor in real-time all shipping
activity taking place in and around
transhipment and the platform itself to
minimize potential disaster
» Ensure consistent, tracking of all
vessels even as offshore activities at
open ocean:
Ability to set geo-fencing based on
real-time location: Shipment,
Queueing, Loading, Unloading and
& Returning
Automatic vessel scheduling and
optimization

10.  The barge rotation algorithm
decomposes the problem into a
voyage allocation part and a
voyage scheduling part, which are
invoked initially to generate a
feasible schedule, and then are
called iteratively in a voyage
improvement heuristic, i.e., a local
search procedure that modifies
the initial allocation decisions.
 The barge rotation algorithm is
comprised of a voyage allocation
(block V) and a voyage scheduling
part (block VI).
 Blocks III-IX iterate between the
two parts, in order to generate
improved feasible solutions
