Meeting The Challenges Of Managing Marine Riser Equipment Using Intelligent
What are kip-days and why they matter
Marine Riser equipment needs to be inspected multiple times during its lifetime to ensure it stays in proper
working order. Marine riser manufacturers require that a non-destructive inspection of the riser joints/couplings
is to be carried out after a specified number of kip-days or time in years, whichever comes first. The amount of
kip-days or time to inspection depends on where the risers are used, and these limits are set
by the manufacturers, e.g. 500000 kip-days/5 years in the North Sea, or 1000000 kip-days/5 years in the Gulf of
Mexico. A kip-day is a fatique indicator that is calculated individually for each riser based on the amount of work
it does. Carrying out inspections based on time alone is simple, but solely basing inspections on time runs the
risk of risers actually surpassing their kip-day limit for inspection, and this is especially likely in deepwater
drilling. This could lead to the riser equipment failing in use and potentially in the loss of a whole
Challenges in calculating kip-days
Every single riser accumulates kip-days at a different rate based on:
- Type of its buoyancy
- Its weight
- Position in the riser string
- Changing top tension
- Mud weight
Keeping track of all these variables for each piece of riser equipment is challenging and if done by hand,
time-consuming. Also traditionally there is no way of tracking this information, so when the riser is transferred
to another rig, the amount of kip-days it has accumulated usually is lost in the progress.
Challenges in riser management across the fleet
Accessing information about the the state and usage of the riser equipment across the fleet or even on individual
rigs, for example on request by insurance companies or classification bodies, may be tedious. The sheer amount of
equipment, fragmented locations, and slow communications may
mean getting answers can become a project in itself.
The solution for the challenges in riser equipment management
BRML Solutions RiserKips Software Suite is a low-cost complete solution to address the challenges in riser equipment management across the whole fleet. It comprises of
3 different components that work in unison to facilitate all facets of riser management and helps prevent
riser failures and unnecessary riser inspections. It tracks the fleet-wide movement and
history of each joint after the last inspection for all involved. The
RiserKips Software Suite is currently deployed and helps manage marine riser equipment on rigs all around the
RiserKips - Riser Field Management software
RiserKips is a tool for to help the top drilling management, Drilling Sup., Subsea Supv., and OIM to manage riser
equipment. RiserKips calculates the kip-days for each individual marine riser equipment based on the individual
attributes of the joint and the amount and type of work done, using formulas from API 16R and 16Q
recommendations. It also helps
Subsea Engineers to create running lists with specific top tensions,manages riser storage and use, and keeps a log
of work and maintenance history. RiserKips can work either stand-alone or it can be coupled with the ORB and REMOS products to allow fleet-wide management.
ORB - Onshore Riser Base software
ORB is a special software designed specifically for onshore bases where inspection, storage and maintenance of equipment takes place. It handles handovers between staff
of the workshop and keeps track of inspection work states so that no time is wasted checking what work has
been carried out.
ORB allows supervisors to easily monitor assigned tasks and the status of individual workers and automatically stores the work history for review and audit. It keeps
track of the amount of work in form of man-hours used on equipment for each individual rig. It also handles
and keeps records of
communication between the base and the rigs to make sure nothing is "lost in translation". ORB
integrates with REMOS online services to allow for easy riser equipment transfer management across the fleet.
REMOS - Riser Equipment Management Online Service
REMOS is an online service for onshore supervisors to help facilitate fleet-wide management of marine riser equipment and assets. It works in conjunction with
RiserKips -enabled rigs and ORB -enabled bases to
provides access to all the information collected at those sites, through a protected secure online service. It
contains tools to help manage and track equipment utilization, transfers, and maintenance across a fleet of rigs.
Usage monitoring is made easy through the use of automatically generated reports and alerts when kip-days, running
days, or ton cycles exceed their individually assigned limits for each piece of equipment.
Having an overview of all inspections across the entire fleet, and lists of upcoming inspections, gives supervisors
required information to plan ahead to make sure everything runs smoothly and efficiently.
The future of marine riser management is here now
The BRML Solutions RiserKips Software Suite has been in development and in use for the past 6 years. It has been designed to be easy to use and intuitive, and easy to
incorporate into existing workflows. It has provided demonstratable time and money-saving benefits across a
fleet rigs around the world. It is the future of marine riser management, now.
